Single transformations of 2-D shapes - rotations

 When we rotate an image, we turn a shape on a point of rotation.  We can turn or rotate the image clockwise or counterclockwise.  The point of rotation will be on one of the vertices of the shape.

Think about the hands on a clock.  When the minute hand moves from the 12 to the 3, it rotates a quarter turn clockwise.


When the minute hand moves from the 12 to the 6, It rotates a half turn clockwise.


When the minute hand move from the 12 to the 9, it rotates a three-quarter turn.

Now that you have seen how to do rotations, on a piece of paper draw a triangle.  Label the vertices A, B and C.  Rotate the triangle a half turn clockwise, and label the vertices on the image.

Draw a square and label the vertices A, B, C and D.  Rotate the square 3/4 turn clockwise and label the image and its vertices.

Draw a shape (not a circle) of your choice. Choose a vertex to rotate your shape 1/4 turn counterclockwise.  Label your image and the vertices.  

Once you have finished, take a picture and email the picture to your teacher!
